  1. Hi @vsethia, I apologize for the delay. Here are the answers to your questions taken from the respective specifications pages for the Analog Discovery 2 (link) and the ADP3450 (link): 1. The Digital IO channel output voltage levels are only programmable for the ADP3450 with a range between 1.2 and 3.3V (with 5V CMOS tolerant inputs) . The AD2 Digital IO are only at 3.3V output (but can measure 1.2V and 5V CMOS inputs) 2. ADP3450 - the digital power supply can have current output up to 300 mA (same 1.2V to 3.3V voltage output range). There is no analog power supply AD2 - analog
  2. Hi @EERE, I apologize for the long delay. I took a look at the schematics and this connectivity should work just fine. You'll have to make sure the modules are connected in the correct orientation of course; it should be that the top side of the pcb of either the Transistor Tester or the Impedance Analyzer is towards the notched side, though I would personally still make a point of verifying that orientation is accurate by checking with a multimeter where the ground pins are located on the expansion header. Let me know if you have any questions. Thanks, JColvin
  3. Hi @mmolter775, Digilent does not have any drawings available that I am aware of since the purpose of the BNC connectors was to help facilitate the higher bandwidth capabilities of the Analog Discovery Pro than flywires can facilitate. I will ask if any such drawings could be made (or published if they happen to exist). There is an unofficial adapter made by another Forum user on this thread that may be of interest to you though: Thanks, JColvin
  4. Hi @Mathieu G., I have sent you a PM with some contact information. Thanks, JColvin
  5. Hi @Quemar, I have sent you a PM with the correct Digilent contact to discuss the licensing options since I do not personally know what they are. Thank you for your patience throughout this process, JColvin
  6. Hi @Quemar, We're not certain of why you are seeing the differences when using Diamond Programmer with the JTAG SMT3. Out of curiosity though, what led you to believe that the Lattice Diamond Programmer tool would be compatible with the Digilent programmers? It does not appear to indicate on the download page for the Diamond Programmer, and this thread and reference page seem to indicate that Digilent based programmers solutions are not compatible with Lattice, nor does Digilent claim this. Thanks, JColvin

    Genesys ZU 3eg

    Hi @Enthusiastic, I don't know why the 2019.1 materials are not readily linked anywhere, but I was able to find some of them through github by looking at their tags, https://github.com/Digilent/Genesys-ZU-HW/tags and https://github.com/Digilent/Genesys-ZU-OS/tags, it didn't look like there was any tags for the software page though. Thanks, JColvin
  8. Hi @shreya2207, If you already the hardware setup to do I2C communication with the Xilinx's I2C PS library, what you will end up needing to do is adjust the library functions (I don't know what the library for the IMU you have is based on or built for) to use the I2C commands that the Xilinx software uses, much like Digilent's I2C based Pmods like the Pmod AQS, https://github.com/Digilent/vivado-library/tree/master/ip/Pmods/PmodAQS_v1_0. Thanks, JColvin

    PMOD RS485 with Zybo

    Hi @mre2all, Yes, those Pmod ports can be used with the Pmod RS485. You can either use a UART controller in HDL to communicate with the Pmod RS485 or if you want to use the IP flow/Zynq processor you can setup an AXI UART IP that connects to the Pmod port of interest that you want to use. Using a high speed Pmod port vs a non-high speed Pmod port should not be an issue in terms of hardware connectivity with the Pmod RS485. Let me know if you have any questions. Thanks, JColvin
  10. Hi @Lorenzo701, I'm not sure if it is possible to directly communicate and control the Arty A7 35T through LabVIEW; the only boards that I am aware of that could be communicated with through LINX (which uses NI VISA as I recall) were some of Digilent's microcontroller boards (which aren't really formally supported anymore as far as I am aware) and Digilent's Zynq boards with an SD card which loads a Raspbian OS, some specialized Digilent files and the LabVIEW Community Edition in order to be able to control the IO pins (further described in this guide here: https://digilent.com/reference/
  11. Hi @Quemar, I asked one of design engineers about this and they assured me that there has not been any changes of any kind to the SMT3. Would you be able to share more detail on how your two versions are set up in terms of the JTAG connectivity and where you measured the TCLK signal so our design engineer can see if anything jumps out at them? Otherwise based on what you have described and considering that the SMT3 is the only programmer on your board (as I understand it) and the Vivado Hardware Manager is correctly driving the JTAG signals in both versions of your systems, thi
  12. Hi @EE Deven, I'm not certain what you mean by "ADI function", but in terms of which Zynq board to recommend, it will depend a little bit on what you are wanting to do. Are you wanting to do some high speed communication, or are you looking to use a "slower" module that communicates over SPI (like a Pmod), or something entirely different? Thanks, JColvin
  13. Hi @Antonio Fasano, The Digilent Sales team would be the best point of contact in terms of discussing returning the products, since I do agree that the information on the store page was unclear about the differences; they have a form that you would be able to fill out here: https://digilent.com/shop/sales-and-order-support/. To be clear, I am not personally able to authorize the return or anything like that, so I do not know what the process will end up looking like (nor do I know the current stock availability). Thanks, JColvin
  14. Hi @jmhbfe, I reached out to another engineer much more familiar with Adept for their input, but neither of us know what might have happened for the host code was suddenly not able to locate the DLLs on the development machine, though I'm glad to hear that you got it working. Thanks, JColvin

    Schematics of Cora Z7

    Hi @thoonky, I don't know what operating system you are using on your PC, but you can look to see if the board is detected on a Windows system by seeing if the COM port and the USB Serial Converter A and USB Serial Converter B show up in the Device Manager (under COM Ports and Universal Serial Bus controllers, respectively). On Linux, you can use lsusb to see if the board shows up; I also know for Vivado installations on Linux based OS's that you will need to manually download the cable drivers separately. I am not sure about how a Raspberry Pi would detect the board. There are some addit
